Tactile maps are a counterpart to Braille--maps for the blind. The lines on tactile maps are raised so that a blind person can trace a route with her fingers. Below see an example of a tactile map as well as a "talking" tactile device. A tactile map is mounted on the talking device, and when the blind person touches a point on the map, the device reads off the place name.

The top map looks like an archaeological plan with columns and rooms! How cool, it's interesting to actually see what you're talking about.
